CB7 (Comic Book 7-Zip) is a modern comic archive that uses 7-Zip's LZMA2 compression algorithm, offering significantly better compression ratios than CBR or CBZ. It is especially useful for high-resolution color comics where file size is a concern. CB7 is supported by most contemporary comic readers and is increasingly chosen for archival purposes. Converting CB7 to standard ebook formats enables reading on devices that do not have 7-Zip decompression capabilities.
Converting CB7 to PDB extracts the sequentially ordered images from the CB7 archive and repackages them within a PDB container. Our conversion service uses Calibre, the gold-standard open-source ebook management tool, ensuring that text encoding, chapter markers, and embedded assets are faithfully transferred. The converted PDB file retains the original book's content and structure for use on compatible devices.
PDB (Palm Database) is the native ebook format for Palm OS devices and eReader applications. Converting to PDB allows content to be read on Palm PDAs, Treo smartphones, and any device running the eReader application. Though Palm OS is obsolete, PDB conversion is still used in digital preservation workflows and by collectors of vintage mobile technology. The compact PDB format is also supported by several modern multi-format e-reader apps.
Comic archives convert to PDB as image sequences. Ensure the archive contains images in correct alphabetical/numerical order, as Calibre relies on filename ordering. High-resolution images produce larger output files; consider resizing images beforehand. PDB is a legacy format primarily for specific historical hardware. Verify your target device supports PDB before converting. For modern devices, EPUB or MOBI are better choices. Our conversion engine processes CB7 to PDB entirely in the cloud — no software installation needed. Files are deleted from our servers within 24 hours of upload.
